For both [bool; 128] and Vec w/ capacity 128, ignoring the header, is it safe to assume that both takes 16 bytes ? If so, where is this documented ? The core issue here is whether a bool is stored as a u8 or if Rust is somehow packing 8 bool's into 1 u8.

[image] anon80458984: The core issue here is whether a bool is stored as a u8 or if Rust is somehow packing 8 bool's into 1 u8. Bool is stored as u8, since we can address individual bools, but can't address anything less then byte.

[bool; 128] and Vec<bool> w/ capaticy 128: both uses 16 bytes (ignoring header)?

@kaj : Agreed, using @H2CO3 's suggestion in Idiomatic way to implement u8 bit utils - #2 by H2CO3
